Thanks for the feedback! We are routing this to the appropriate team for follow-up. cc @kushagraThapar @pjohari-ms @TheovanKraay.

@varenyavv I investigated this issue and couldn't reproduce it with Netty's leak detection code enabled. I investigated on the LATEST version of azure-cosmos. I have the code here - https://github.com/kushagraThapar/cosmos-java-sdk-testing/blob/main/src/main/java/com/example/common/NettyMemoryIssue.java

The only difference is, I am not using the payload you mentioned. Do you think the issue is strictly related to the payload type and size?

Apologies for the delayed response. I attempted to replicate the issue locally but was unsuccessful. The error occurred specifically in our production environment, prompting us to revert to version 4.53.1, which has been stable since then. We'll proceed to test the latest version in our staging environment to determine if the issue persists. By the way, could this happen due to networking issues?

Thanks @varenyavv for trying it out. Let us know how it goes in staging environment, I will keep this issue open.
NOTE: It can happen because of networking issue because that could leave some of the buffers hanging, but having a repro would be the first step to look into it deeper.
